StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 July 2026; the live site may have changed since.

Purple Hammer is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on July 28, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 6 weeks before launch. The crawl picked up 6 technologies on this site, covering DNS providers, business email, transactional email, and seo. The stack includes Cloudflare DNS, Google Search Console, and Google Tag Manager.
